The Diesel Workhorse™

For demanding jobs that call for highamperage capabilities, the SAE-400® offers400 amps for DC stick welding and 3,000watts of AC power. The SAE-400® ispowered by either a heavy duty Perkins® orDeutz® industrial diesel engine. Bothengines offer low maintenance and long lifefor hassle-free operation. Add CV wirewelding with the optional CV Adapter.

FEATURESRugged Construction- Heavy gauge steel case withstands

rough field handling.Dual Continuous Output Control- Continuous adjustment of voltage and

current.- Select either a soft “buttery” arc or

snappy “digging” arc for fast, high-quality welding.

Arc Gouging- Arc gouging with up to 3/8 in.

(10 mm) carbons.Multiple Arcs- Large-capacity DC weld output makes

the SAE-400® the #1 choice formultiple arcs with the Multi-Weld™

350 system. Available power is22,500 watts at 60V DC. (Seerecommended accessories section.)

K1278-14 has Euro and NEMAreceptacles for 60 Hz AC generatorpower (K1278-10 has NEMAreceptacles only).

- 3,000 watts for both models.
